Wrong OS for Keyboard Driver

I purchased an (outdated but new) Palm m515 PDA because there were available
(outdated but new) keyboards for it that I could operate while on my back
during all of the next 6 months. Now I found out that the driver needs Win
95/98/2000/ME or NT. My OS is Win XP sp2. Both PDA and keyboard are outdated
enough that there is no longer any telephone or online support system. Is
there a way to load the ThumBoard driver on my computer (and thus my PDA)
with the Windows XP system? Any options that anyone knows of?
